DETAILED DESCRIPTION

The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of various embodiments of the invention as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the various embodiments described herein can be made without departing from the scope and spirit of the invention.

The use of the terms first, second, etc. do not denote any order or importance, but rather the terms first, second, etc. are used to distinguish one element from another. Like numerals refer to like elements throughout. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being “on” another element, it can be directly on the other element or intervening elements may also be present. It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise.

It will be further understood that the terms “includes” and/or “including”, when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. It will be understood that when an element or layer is referred to as being “on”, “connected to” or “coupled to” another element or layer, it can be directly on, connected or coupled to the other element or layer or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly connected to” or “directly coupled to” another element or layer, there are no intervening elements or layers present.

It will be understood that, although the terms “first,” “second,” “third” etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, “a first element,” “component,” “region,” “layer” or “section” discussed below could be termed a second element, component, region, layer or section without departing from the teachings herein.

Furthermore, relative terms, such as “lower” or “bottom” and “upper” or “top,” may be used herein to describe one element's relationship to another element as illustrated in the Figures. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the Figures. In an exemplary embodiment, when the device in one of the figures is turned over, elements described as being on the “lower” side of other elements would then be oriented on “upper” sides of the other elements. The exemplary term “lower,” can therefore, encompasses both an orientation of “lower” and “upper,” depending on the particular orientation of the figure. Similarly, when the device in one of the figures is turned over, elements described as “below” or “beneath” other elements would then be oriented “above” the other elements. The exemplary terms “below” or “beneath” can, therefore, encompass both an orientation of above and below.

“About” or “approximately” as used herein is inclusive of the stated value and means within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art, considering the measurement in question and the error associated with measurement of the particular quantity (i.e., the limitations of the measurement system). For example, “about” can mean within one or more standard deviations, or within ±30%, 20%, 10%, 5% of the stated value.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the invention, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Exemplary embodiments are described herein with reference to cross section illustrations that are schematic illustrations of idealized embodiments. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, embodiments described herein should not be construed as limited to the particular shapes of regions as illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. In an exemplary embodiment, a region illustrated or described as flat may, typically, have rough and/or nonlinear features. Moreover, sharp angles that are illustrated may be rounded. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region and are not intended to limit the scope of the claims.

Hereinafter, the invention will be explained in detail with reference to the accompanying drawings.

FIG. 1A is a perspective view showing a display device 10 according to an exemplary embodiment of the invention and FIG. 1B is an exploded perspective view showing the display device 10 according to an exemplary embodiment of the invention.

Referring to FIGS. 1A and 1B, the display device 10 includes a curved display module 100 and a stand 200. The curved display module 100 receives an image signal ES (refer to FIG. 2) and displays an image. The curved display module 100 is attachable to and detachable from the stand 200. The curved display module 100 includes a signal receiver 110 to receive the image signal ES (refer to FIG. 2). The signal receiver 110 receives various electrical signals including a power source signal from a signal transmitter 210 in addition to the image signal ES (refer to FIG. 2). The curved display module 100 does not display the image in the case where the image signal ES (refer to FIG. 2) is not provided from the stand 200.

The curved display module 100 is partially accommodated in a groove GR and stood to allow an exit surface 101 (refer to FIG. 3) to face a user. The curved display module 100 may be bent. The curved display module 100 may be curved. The curved display module 100 is concaved when viewed in an exit rear surface direction DR2 from the exit surface 101 (refer to FIG. 3) to an exit rear surface 102 (refer to FIG. 3), i.e., when viewed from the point O (refer to FIG. 3), but it should not be limited thereto or thereby. That is, the curved display module 100 may be convex when viewed in the exit rear surface direction DR2. The curved display module 100 may be rigid or flexible. The term “flexible” used herein means that the curved display module 100 is bendable, and thus the curved display module 100 may be completely folded or partially bent.

In the illustrated exemplary embodiment, the display device 10 includes the curved display module 100, but the display device 10 may include a flat display module according to other exemplary embodiments.

The groove GR in which a portion of the curved display module 100 is accommodated is defined in the stand 200 which provides the curved display module 100 with the image signal ES (refer to FIG. 2). The stand 200 may fix the curved display module 100 thereto. The signal transmitter 210 is disposed in the groove GR to generate the image signal ES (refer to FIG. 2). The signal transmitter 210 applies the various electrical signals including the power source signal in addition to the image signal ES (refer to FIG. 2).

The groove GR may have a bent or curved shape. The portion of the curved display module 100 is accommodated in the groove GR.

In FIGS. 1A and 1B, the image signal ES (refer to FIG. 2) is applied to the signal receiver 110 of the curved display module 100 from the signal transmitter 210 of the stand 200 when the signal transmitter 210 contacts the signal receiver 110, but it should not be limited thereto or thereby. In another exemplary embodiment, the image signal ES (refer to FIG. 2) may be applied to the signal receiver 110 of the curved display module 100 from the signal transmitter 210 of the stand 200 in wireless communication system. Accordingly, the image signal ES (refer to FIG. 2) may be applied to the signal receiver 110 of the curved display module 100 from the signal transmitter 210 of the stand 200 even when the signal transmitter 210 does not contact the signal receiver 110.

FIG. 2 is a block diagram showing a display device according to an exemplary embodiment of the invention.

Referring to FIG. 2, the stand 200 includes the signal transmitter 210 and an electrical module 220A. The signal transmitter 210 receives a main control signal MCS from the electrical module 220A and applies the image signal ES to the signal receiver 110.

The electrical module 220A includes a display device controller 221, a broadcast receiver 222, an audio output part 223, a user input part 224, a user identifier 225, an external device interface 226, a network interface 227, a content synchronizer 228, and a storing part 229. In other exemplary embodiments, at least one of the broadcast receiver 222, the audio output part 223, the user input part 224, the user identifier 225, the external device interface 226, the network interface 227, the content synchronizer 228, and the storing part 229 may be omitted in the electrical module 220A.

The broadcast receiver 222 may receive a broadcast content and a streaming content indicating retransmission of the broadcast content. The broadcast content is provided from a broadcast station and the streaming content is provided from a streaming server. In exemplary embodiments, the streaming server may be a variety of servers that provides the broadcast content, e.g., a live broadcast, a recorded broadcast, etc., or various moving image contents in a streaming mode.

The broadcast receiver 222 includes a tuner 222A and a demodulator 222B. The tuner 222A selects a radio frequency (“RF”) broadcast signal corresponding to a channel selected by the user or all predetermined channels among RF broadcast signals received through an antenna. In addition, the tuner 222A converts the selected RF signal to an intermediate signal, a base band image, or a voice signal, for example. In an exemplary embodiment, in the case where the selected RF broadcast signal is a digital broadcast signal, the tuner 222A converts the selected RF broadcast signal to a digital IF signal, and in the case where the selected RF broadcast signal is an analog broadcast signal, the tuner 222A converts the selected RF broadcast signal to an analog base band signal or the voice signal, for example. The tuner 222A processes the digital broadcast signal or the analog broadcast signal. In exemplary embodiments, the tuner 222A receives the RF broadcast signal with a single carrier according to an advanced television system committee (“ATSC”) manner or the RF broadcast signal with carriers according to a digital video broadcasting (“DVB”) manner, for example.

The demodulator 222B receives the converted digital intermediate frequency (“IF”) signal from the tuner 222A and performs a demodulation operation on the converted digital IF signal. The demodulator 222B outputs a stream signal after performing demodulation and channel decoding. The stream signal may be obtained by multiplexing the image signal, the voice signal, or the data signal. The stream signal output from the demodulator 222B is applied to the display device controller 221.

The display device controller 221 performs a demultiplexing process, an image signal process, and a voice signal process, and then applies the image signal ES to the curved display module 100.

The audio output part 223 outputs a sound corresponding to the image displayed in the curved display module 100. The audio output part 223 receives a sound-processed signal from the display device controller 221 and outputs the sound. In an exemplary embodiment, the audio output part 223 may be provided as a speaker, for example.

The user input part 224 applies a control command generated by the user to the display device controller 221 or applies a signal provided from the display device controller 221 to the user.

In an exemplary embodiment, the user identifier 225 includes a device for recording visual images such as a camera. In an exemplary embodiment, the user identifier 225 takes a visual image (e.g., a photograph) of the user with the camera and identifies the user on the basis of the visual image. Image information taken with the camera may be input to the display device controller 221.

The external device interface 226 transmits or receives data to or from an external device connected to the external device interface 226. In exemplary embodiments, the external device interface 226 may include a wireless communication system, an audio/visual (“A/V”) input/output unit, a universal serial bus (“USB”) port terminal, a high definition multimedia interface (“HDMI”) connection terminal, an RGB connection terminal, etc., for example. In exemplary embodiments, the external device interface 226 is connected to the external device, e.g., a digital versatile disc (“DVD”), a blue ray disc, a game unit, a camera, a camcorder, a computer, a notebook computer, a set-top box, etc., in a wire or wireless communication, and performs input and output operations with the external device. The A/V input/output unit receives the sound and image signals from the external device. The wireless communication system performs a short-range wireless communication with other electronic devices,

The network interface 227 provides an interface to connect the display device 10 to a wire or wireless network provided with an internet connection. In exemplary embodiments, the network interface 227 receives contents or data provided by an internet network, a content provider, or a network operator, for example.

The content synchronizer 228 allows the image to be displayed in the curved display module 100 in synchronization with a synchronization reference time provided from a content synchronization server. The synchronization reference time is set on the basis of content identification information. In an exemplary embodiment, the content synchronizer 228 may include a memory to store the received image contents.

The storing part 229 stores a program to process and control signals in the display device controller 221 or stores the signal-processed image, voice, or data signal. The storing part 229 may temporarily store the image, voice, or data signal applied to the external device interface 226. In an exemplary embodiment, the storing part 229 may store information about broadcast channels using a channel memorizing function, e.g., a channel map.

In a conventional display device, at least one of the display device controller, the broadcast receiver, the audio output part, the user input part, the user identifier, the external device interface, the network interface, the content synchronization part, and the storing part, which are included in the electrical module, is included in the display module, so that the display module is difficult to be substantially slim.

According to the display device according to the illustrated exemplary embodiment, the electrical module used to drive the display module is included in the stand, and thus the display module may be substantially slim.

The curved display module 100 includes the signal receiver 110, an image display part DP, an image display part controller 115, a data driver 116, and a gate driver 117. The signal receiver 110 receives the image signal ES from the signal transmitter 210. The image display part DP displays the image.

The image display part controller 115 controls a drive of the data driver 116 and the gate driver 117. The image display part controller 115 receives input image signals RGB and control signals CS from the signal receiver 110. The image display part controller 115 converts a data format of the input image signals RGB to a data format appropriate to an interface between the panel controller 115 and the data driver 116 and the structure of the image display part DP to generate output image data ID and applies the output image data ID to the data driver 116.

The image display part controller 115 generates a gate control signal GCS, such as a vertical start signal, a vertical clock signal, a vertical clock bar signal, etc., and a data control signal DCS, such as an output start signal, a horizontal start signal, etc., on the basis of the control signals CS. The gate control signal GCS is applied to the gate driver 117 and the data control signal DCS is applied to the data driver 116.

The data driver 116 converts the output image data ID to data voltages in response to the data control signal DCS provided from the image display part controller 115 and outputs the data voltages. The data voltages output from the data driver 116 are applied to the image display part DP.

The gate driver 117 sequentially outputs gate signals in response to the gate control signal GCS provided from the image display part controller 115.

The image display part DP includes a plurality of gate lines GL1 to GLn, a plurality of data lines DL1 to DLm, and a plurality of pixels PX. FIG. 2 shows only first and n-th gate lines GL1 and GLn among the gate lines GL1 to GLn as a representative example. In addition, FIG. 2 shows only first and m-th data lines DL1 and DLm among the data lines DL1 to DLm as a representative example.

The gate lines GL1 to GLn are connected to the gate driver 117 to receive the gate signals from the gate driver 117. The data lines DL1 to DLm are connected to the data driver 116 to receive the data voltages from the data driver 116.

The pixels PX are arranged in a matrix form. In an exemplary embodiment, the pixels PX display at least one of primary colors of red, green, and blue colors, for example. However, the colors displayed by the pixels PX should not be limited to the red, green, and blue colors. That is, the pixels PX may further display secondary primary colors of white, yellow, cyan, and magenta colors, for example, in addition to the red, green, and blue colors.

The pixels PX display a unit image, and a resolution of the image display part DP is determined depending on the number of the pixels PX arranged in the image display part DP. FIG. 2 shows only one pixel PX as a representative example, and others are omitted.

Each pixel PX is connected to a corresponding gate line among the gate lines GL1 to GLn and a corresponding data line among the data lines DL1 to DLm.

FIG. 3 is a perspective view showing the curved display module 100 included in the display device 10 according to an exemplary embodiment of the invention.

Referring to FIGS. 1A, 1B, and 3, the curved display module 100 has a first curvature radius R1. In an exemplary embodiment, the first curvature radius R1 is in a range from about 2000 millimeters (mm) to about 5000 mm, for example. When the first curvature radius R1 is smaller than about 2000 mm, the image displayed in the curved display module 100 is difficult to be perceived by the user, and when the first curvature radius R1 exceeds about 5000 mm, a three-dimensional effect, immersiveness, and a presence of the image displayed through the display device 10 are degraded.

In FIG. 3, for the convenience of explanation, the curved display module 100 has a curved rectangular shape, but at least one surface of an exit surface 101, an exit rear surface 102, an upper surface 103, a lower surface 104, a first side surface 105, and a second side surface 106 of the curved display module 100 may have a stepped shape.

The curved display module 100 includes the exit surface 101, the exit rear surface 102, the upper surface 103, the lower surface 104, the first side surface 105, and the second side surface 106. The exit surface 101 is defined by one surface of the image display part DP (refer to FIG. 4A) and one surface of the frame FM (refer to FIG. 4A) surrounding the one surface of the image display part DP (refer to FIG. 4A). The exit rear surface 102 is defined by the other surface of the image display part DP (refer to FIG. 4A) and the other surface of the frame FM (refer to FIG. 4A) surrounding the other surface of the image display part DP (refer to FIG. 4A). Each of the upper surface 103, the lower surface 104, the first side surface 105, and the second side surface 106 may be a side surface connecting the one surface of the frame FM (refer to FIG. 4A) and the other surface of the frame FM (refer to FIG. 4A).

The exit surface 101 exits the image through at least a portion thereof. The exit surface 101 is curved. The exit surface 101 is concaved when viewed from the exit surface 101 to the exit rear surface direction DR2, i.e., when viewed from the point O, but it should not be limited thereto or thereby. That is, in another exemplary embodiment, the exit surface 101 may be convex when viewed from the exit surface 101 to the exit rear surface direction DR2. The exit surface 101 may have the first curvature radius R1. A portion of the exit surface 101 is accommodated in the groove GR.

The exit rear surface 102 faces the exit surface 101. A portion of the exit rear surface 102 is accommodated in the groove GR. The exit rear surface 102 is curved. The exit rear surface 102 is concaved when viewed from the exit surface 101 to the exit rear surface direction DR2, but it should not be limited thereto or thereby. That is, the exit rear surface 102 may be convex when viewed from the exit surface 101 to the exit rear surface direction DR2. Although not shown in figures, a curvature radius maintaining member may be provided to maintain the curvature radius of the other portion of the exit rear surface 102, which is not accommodated in the groove GR.

In FIGS. 1A and 3, the curvature radius of the exit surface 101 from the point O is smaller than the curvature radius of the exit rear surface 102, but it should not be limited thereto or thereby. That is, the curvature radius of the exit surface 101 may be greater than the curvature radius of the exit rear surface 102. In FIGS. 1A and 3, the exit surface 101 has substantially the same shape as that of the exit rear surface 102 and substantially the same size as that of the exit rear surface 102, but it should not be limited thereto or thereby. That is, the shape and size of the exit surface 101 may be different from the shape and size of the exit rear surface 102.

The upper surface 103 faces the lower surface 104. The upper surface 103 is connected to the exit surface 101 and the exit rear surface 102. In an exemplary embodiment, the upper surface 103 may be curved when viewed in a plan view, for example. In FIGS. 1A and 3, the upper surface 103 has substantially the same shape as that of the lower surface 104 and substantially the same size as that of the lower surface 104, but it should not be limited thereto or thereby. That is, the shape and size of the upper surface 103 may be different from those of the lower surface 104.

The lower surface 104 is connected to the exit surface 101 and the exit rear surface 102. The lower surface 104 may be curved.

In the case where the length L2 in the horizontal direction of the stand 200 exceeds about 5/3 of the length L1 in the horizontal direction of the curved display module 100, the stand 200 takes up excessive space, and thus the stand 200 is difficult to be a useful appliance. In an exemplary embodiment, referring to FIGS. 11A and 11B, the length L1 in the horizontal direction of the stand 200 may be greater than the length L1 in the horizontal direction of the curved display module 100, for example. Referring to FIG. 11A, the groove GR is defined by four side surfaces and one bottom surface, and referring to FIG. 11B, the groove GR is defined by two side surfaces and one bottom surface. Referring to FIG. 11C, the length L2 in the horizontal direction of the stand 200 may be equal to the length L1 in the horizontal direction of the curved display module 100. Referring to FIG. 11D, the length L2 in the horizontal direction of the stand 200 may be less than the length L1 in the horizontal direction of the curved display module 100.

FIGS. 12A and 12B are perspective views showing a display device including a curved display module and FIGS. 13A and 13B are perspective views showing a display device including a curved display module having a curvature radius smaller than that of the curved display module shown in FIGS. 12A and 12B.

Referring to FIGS. 12A, 12B, 13A, and 13B, the stand 200 has a curvature radius that is variable corresponding to curvature radiuses r1 and r2 of the curved display module 100. According to the display device 10 of the invention, curved display modules having the curvature radiuses r1 and r2 different from each other may be fixed to one stand 200. In FIGS. 12A, 12B, 13A, and 13B, two curved display modules having different curvature radiuses are fixed to one stand 200, but they should not be limited thereto or thereby. That is, although one curved display module has a variable curvature radius, the one curved display module having the variable radius may be fixed to one stand.

The stand 200 includes a plurality of blocks 281 and a plurality of block connection parts 283. A curvature radius of the groove GR may be controlled using the blocks 281 and the block connection parts 283 to correspond to the curved display module 100. The curvature radius r1 of the curved display module form the point O1 shown in FIG. 12A may be smaller than the curvature radius r2 of the curved display module 100 form the point O2 shown in FIG. 13A. In an exemplary embodiment, the curvature radius of the groove GR of the stand 200, to which the curved display module 100 is fixed in consideration of the curvature radius r1 of the curved display module 100 shown in FIG. 12A, may be controlled to correspond to the curvature radius r2 of the curved display module 100 shown in FIG. 13A, for example. Therefore, the curved display module 100 shown in FIGS. 12A and 12B and the curved display module 100 shown in FIGS. 13A and 13B may be selectively fixed to the one stand 200 without using a separate stand.

In FIGS. 12A, 12B, 13A, and 13B, the curvature radius of the groove GR is controlled by the blocks 281 and the block connection parts 283, which are included in the stand 200, but it should not be limited thereto or thereby. That is, the stand 200 may have various other shapes as long as the curvature radius of the groove GR may be controlled to correspond to the curvature radius of the curved display module 100.

FIG. 14A is a perspective view showing a display device 10 including an auxiliary stand according to an exemplary embodiment of the invention, and FIG. 14B is an exploded perspective view showing a display device including an auxiliary stand according to an exemplary embodiment of the invention.

Referring to FIGS. 14A and 14B, the display device 10 may further include an auxiliary supporter 290. The auxiliary supporter 290 assists to accommodate and fix the curved display module 100 into the stand 200. In an exemplary embodiment, a portion of the auxiliary supporter 290 is accommodated in the groove GR to prevent the curved display module 100 from being separated from the stand 200, for example. As show in FIG. 14A, the auxiliary supporter 290 has substantially an L-shape in a side view, but it should not be limited thereto or thereby. The auxiliary supporter 290 may have various other shapes as long as the auxiliary supporter 290 assists to fix the curved display module 100 to the stand 200. In addition, FIGS. 14A and 14B show one auxiliary supporter 290, but the auxiliary supporter 290 may be provided in a plural number according to other exemplary embodiments. The display device according to the illustrated exemplary embodiment includes the stand in which the lower portion of the curved display module is accommodated. Thus, the curved display module may be fixed to the stand without increasing the thickness of the curved display module. Accordingly, the display device according to the exemplary embodiment of the invention may be substantially slim.

In addition, according to the display device, the signal receiver is included in the curved display module and the signal transmitter is included in the stand. Therefore, although the signal receiver or the signal transmitter is out of order or defective, the defective signal receiver or the defective signal transmitter may be repaired or replaced with another signal receiver or another signal transmitter after the curved display module is separated from the stand. That is, in the case where defects occur in a conventional display device, the display device is required to be replaced. However, according to the display device of the invention, any one of the curved display device and the stand, in which defects occur, is required to be replaced.

Although the exemplary embodiments of the invention have been described, it is understood that the invention should not be limited to these exemplary embodiments but various changes and modifications can be made by one ordinary skilled in the art within the spirit and scope of the invention as hereinafter claimed.
